14 RC Programming
Elevator (Tilt)
For tilting the helicopter, use the elevator function. For tilting forward, the two aileron servos move down-
ward and the backward elevator servo moves upward. The elevator servo moves twice as much as the
two aileron servos.

Programming 120° CCPM
As the programming procedure varies with different types of R/C systems, it is necessary for you to refer
to the instruction manual of your R/C system. Here are only a few general guidelines which apply to most
systems.
Servo Centering with Sub-Trim Function
As indicated in the above sections on mounting the servos, it is important that the servo arms are exactly
centered. You should use the servo sub-trim function of your R/C system for this purpose.
Activating 120° CCPM
Likely, the 120° CCPM function is initially disabled in your R/C transmitter software and needs to be
separately activated. Please refer to your R/C system manual, where you will also find information on
which channels should be used for the elevator servo and the two roll servos. It is important that you stick
with the requirements stated in the manual. Otherwise the 120° CCPM will not function properly.
Your R/C may support various different CCPM mixings. For Logo 10 choose the 120° mixing with two roll
servos in the front and one elevator servo in the back.
Use the relevant menus for setting the mixing proportions for roll, elevator and pitch functions. Begin by
setting the mix values to 50% each. Higher mix values give higher servo travel for that function This can
have the unwanted result that the swashplate reaches its mechanical limits and causes damage to the
servos or rods or to the swashplate.
If necessary, you may use the CCPM menu to reverse the direction of the function. This is necessary, for
example, if the swashplate tilts to the wrong side or the pitch function is inverted.
The menu for reversing servo functions can be used for reversing the movements of individual servo
arms, but not for reversing the entire control function and of all the involved servos.
